The relative performance of one genotype is not identical in different environments due to genotype-environment interaction (G×E). Thus, for a breeding program to successfully develop cultivars, it is fundamental that candidate elite-lines are teste

Determination of Minimum Number of Growing Seasons for Assessment of Disease Resistance Stability in Rice

Autor: F. Correa-Victoria, Elcio Perpetuo Guimaraes, G. Lema, María Cristina Amézquita

Publikováno v: Crop Science. 38:67-71

The literature reports that evaluations over a number of growing seasons are required to identify stable disease resistance in rice (Oryza sativa L.). CIAT's Rice Breeding Program aims to develop lines with stable resistance; therefore, the knowledge
